small clarification

[Rajanikanth Dandamudi]

Hello,

   I   had  a small doubt.  I   don't whether it  is   a reasonable or
   unreasonable  doubt, but I  want to get  it clarified.  What is the
   reason behind not having  a  builtin function(something similar  to
   join, grep, chomp) in perl to find the current working directory. I
   am  aware of having  a  perl module Cwd.pm,   which has a  function
   cwd(),by which  we can find  out the  current working directory. Is
   there any specific reason behind not having builtin function.

Thanks and Regards,
Rajanikanth
